David Letterman

Paris Hilton was on 'Late Night With David Letterman' on May 2 (promoting herself, as usual) when talk turned to the Lohan clan and Paris' revolving-door love life.

David Letterman pulled zero punches when forced to interview Lindsay Lohan for 'The Late Show' last night (April 9), making the starlet visibly uncomfortable at certain points. Thing is, Letterman's so affable that it was hard for her to stay mad at him.

Comedienne and all-around awesome person with boobs Amy Poehler was on 'Late Night With David Letterman' earlier this week, where she talked about Vice President Joe Biden's cameo on her show 'Parks and Recreation' -- and got a big smooch from Letterman in the process.

Maroon 5 hit the stage of ‘The Late Show With David Letterman’ on Tuesday night (June 26), the same day their latest platter ‘Overexposed’ dropped. They performed their smash single ‘Payphone’ while bathed in alternating blue and yellow lights. There’s no better promotional effort for a new album than appearing on a late night talk show — and the band made the most of it.
